GUI size slider and retina checkbox.

Atlanta said that I should make here a topic, so this suggestion is about graphical user interface (chat, menus, etc) size and high resolution (big displays and retina) support.
It would be great if we were able to adjust GUI size, like graphic quality (I don't talk about sound sliders because they don't have "stops" in movement). This slider could be placed in "Game" tab in options or in "Video" tab.
This could resolve some troubles when you play on high resolution like 2560x1600 ~3mb.
The second thing is Retina support, right now game works like any other app without it. In windowed mode all pixels are doubled screenshot of windowed 1024x640 ~2mb. In some kind this is awesome, that you could play in big window with fast performance resolution, so I think that retina support should appear in option like checkbox, for example "fullscreen" or "vertical synchronisation".
Thanks.

:p
But what do you think about GUI size?
I prefer to play windowed.

I'd actually like to have a slider so I can SHRINK my GUI. It gets in the way a lot and I end up just hitting shortcut keys to get through menus instead of clicking stuff. The only time is click when I want a sword, and I can always just go ahead and have two DPI settings on my mouse. One for playing and one for navigating menus.
Addition: Make the slider range from (Shrink) 50% to (normal) 100% to (grow) 200%. GUI scaling from x/2 to 2x.

Yes, that's what I am talking about, with 1024x640 resolution half of the screen is covered by GUI. Slider move could be separated to five steps: 25%, 50%, 100%, 150%, 200% - that would fit more resolutions.
The 100% size could be current or it's better to be the same for all resolutions in comparing to character size (which is the same at all resolutions).

Ewbte = a cutiey = good suggestion would be pretty nice =0
And that's why we should not buy apple's retina display :P
Just scale down your screen resolution, and fullscreen will work proper.
Retina display and approximate 1280x720 works about the same
